CHARLES E. BARLING, OF SAN FRANCISCO, CALIFORNIA.

CONCENTRATING OR SEPARATING MACHINE FOR MINERALS.

SPECIFICATION forming part of Letters Patent No. 5 46,001, dated September 10, 1895.

Application filed November 8, 1394- Serial No. 528,212. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES E. BARLING, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented certain new and useful Improvements in Concentrating or Separating Machines for Minerals; and I hereby declare the following specification and the drawings therewith to be a complete description of my invention, with the manner of constructworking area of bateas or pans for separating or concentrating minerals, such as magnetic sands or crushed ores, containing metallic particles or concentrates, also to produce a continually-changing and more effective movement of the contents of such pans, and to render their operation continuous and automatic,

both as to feed and discharge of the materials treated. The batea or hand-operated pan has always remained the most effective among implements for separating or concentrating mineral particles from sand or crushed ore, but attempts to apply the same method by machine action have been less successful because of the limited working area of the pans.

In my invention there is a close analogy to hand-operatin g, by reason of an oscillating and undulating motion that at intervals permits a discharge over the edge of the pans and changes them continually as to their level or horizontal position, the sam e as when operated by hand.

Referring to the drawings, Figure l is a plan view of a machine constructed according to my invention. Fig. 2 is a central longitudinal section through Fig. 1. Fig. 3 is an end view and partial section of Figs. 1 and 2. Fig. 4 is a central transverse section through Figs. 1 and 2.

Similar letters of reference indicate corresponding parts in the various figures of the drawings.

The machine as shown is dual, in two parts, the purpose being to include in as small a space as possible a number of batea pans, the main supporting-frameA,maindriviug-shaftB,and some other details performing a double function. forboth sides or halves of the machine.

The number of pans shown on each side is four; butit is evident that this number may be more orless, as the requirements may demand, a single pan answering in some cases and a dozen or more in other cases, the operative elements and action being the same, irrespective of number. The main frame A is a rectangular structure, on which is mounted centrally a main driving-shaft B, having driving-pulleys T, as shown in Figs. 1 and 4:. On the top ofthis main or fixed frame A are two movable frames C C, resting on rollers a, set in the main frame A, as shown in Fig. 2. C C are given a rapid reciprocating motion by means of the eccentrics D D and connecting-links E E, attached to the bottom of the frames C, as shown at F in Figs. 1 and 2.

On top of the frames C C are two other frames G G, pivoted and supported by the hinges 6, so the frames C and G move together longitudinally, but permit a vertical move- Extending the whole length of the main frame A are two shafts H H. These shafts are driven by tangent pinions I I. (Seen in Fig. 4 and one one side in Fig. 1.) These pinions I I are engaged by worm or screw pinions J J on the main driving-shaft B. This produces slow rotation of the shafts H, the speed in relation to the shaft B being as the number of teeth in the tangent pinions I I.

On the ends of the shafts H H are cranks or eccentrics K and connecting-links L, can tending up tostuds M on the top frames G G. To accommodate the longitudinal movement of the connected frames 0 and G, the links L have pivotal bearings at both ends, as seen in Fig. 3, and the upper ends thereof move in the arcs indicated by the dotted lines I) in Fig. 2. This produces an undulating movement of the frames G G and the pans O mounted thereon.

These movable frames ment ofthe outer edges of the frames G in the followingmanner:

The pans O are preferably made of sheet metal, having form as shown in two planes in Figs. 2 and 3 and in the plan at Fig. 1. On the inner or delivery side of these pans they are scalloped, as shown at N, Figs. 1 and 2, so that when the frames Gr are elevated by the links L the waste material at the top of the contents of the panspours over this notch or scallop N, falls into the trough P, and is conducted away to a dump or place of deposit. Material to be treated-such as sand, pulp, or comminuted oreis fed to the pans 0 from a trough Q by spouts R, or in any other suitable manner, Water being supplied with the material either in the trough Q or to the pans O, as may be most convenient.

While amalgamation is not required in the ordinary working of my improved apparatus, quicksilver can be used in the pans, if so desired, and in treating mobile material, such asdrymagnetic sand, water can be dispensed with and the process of selection or concentration be carried on dry.

The frames 0 and Gcan be given a jarring motion by means of notches c in the bearingrails s, resting on the rollers, as seen in Fig. 2.

It will thus be seen that the batea pans O are given a lateral or reciprocating motion and undulating motion at the same time, and are continually changing their position and discharging from the top at regular intervals; also are given ajarring motion, when required, thus imitating as nearly as possible by machine action the method of operating such pans by hand, avoiding by a combination of these movements the compacting of the material on the bottom or at the sides of the pans, the whole being continually mobile and separation continuous.

Having thus described the nature and objects of my invention and the manner of applying the same, what I claim as new, and desire to secure by Letters Patent, is-

1. In a mineral concentrating machine, the combination of a fixed frame, a superposed reciprocating frame, a second frame mounted on the reciprocating frameand hinged at one edge, said frame having a canting motion, the pans carried by the hinged frame, and mechanism for imparting motion to the two frames so that the pans may have an undulating motion, substantially as described.

2. In a mineral concentrating machine, the combination of a fixed frame, a super-posed. reciprocating frame, asecond frame mounted on the reciprocating frame, said frame being hinged at one edge and occupying an inclined position, vertically movable links for imparting to it a canting motion, a series of pans on the latter frame, a trough into which the pans discharge, and a spout for supplying material to the pans, substantially as described.

3. In a mineral concentrating machine, the combination of a fixed frame, a superposed reciprocating frame, amain driving shaft, eccentrics thereon which actuate the reciprocating frame, a hinged inclined frame on the reciprocating frame having a canting motion, a shaft parallel to the hinged frame and geared to the main shaft, eccentrics on the ends of the parallel shaft, and links pivoted to the hinged frame and actuated by said eccentrics, and pans on the hinged frame, substantially as described.

In testimony whereof I have hereunto affixed my signature in the presence of two witnesses.
